6.

The MTM5400 mobile terminal has the option of a GPS board. If a GPS or combined 

TETRA/GPS antenna is used, make sure that the antenna has a clear view to the sky and 
that the antenna base which carries the GPS receiver is not covered with any metallic or radio 
frequency absorbing material.

Antenna Installation Procedure

1.

Mount the antenna according to the instructions provided with the antenna kit. Run the 
coaxial cable to the radio mounting location. If necessary, cut off the excess cable and install 
the cable connector.

2.

Connect the antenna cable connector to the radio antenna connector on the rear of the radio.

3.

If applicable, connect the GPS antenna to the GPS antenna connector PMKN4114 on the rear 

side of the radio.

Completing the Installation

1.

Mount the microphone clip to a convenient spot near your radio.

2.

If your microphone has a telephone-type connector at the end of its cord, plug this connector 

into the 10-pin TELCO connector of your Junction Box.

3.

To complete your radio installation, plug the power cable into the radio power connector.

Any two metal pieces rubbing against each other (such as 
seat springs, shift levers, trunk and hood lids, exhaust 
pipes, and so forth) in close proximity to the antenna can 
cause severe receiver interference.

DO NOT use the 10-pin TELCO connector of Data 
Expansion Head Enhanced or Remote Head Enhanced 
to plug in a microphone.
